UNITED f- STATES PATENT; OFFICE BENJAMIN BILAIKMOIBE,V 0F v(.YUYAHOGA FALLS,v OHIO RADIATOR application niea .inne 7, 1929. Aserial m. :$69,150.

.This invention relates to new and novel improvements in radiators and while intended for use generally wherever Iit may be advantageously applied, it is particularly toprovide a construction which wi adapted for use in heating radiators in which connection it will be illustrated in the drawings and herein described.

'Objects' of the invention are to provide a, strong, durable radiator of simple, con- '10 struction which may-be manufactured at a low cost and which will be very efficient in use.

A particular Objectis to provide a radiator composed ofv laminae of relatively thin 1.5 sheet metal hel/d in lflat abutting relation to form a laminated radiator of Igreat strength and durability.y

Further objects are to rovide a laminated radiator built up o `a plurality of` sheets of metal and which may be quickly and conveniently formed by stamping and l require a minimum of different stampings which in consequence may be providedwith a low cost, 'of die and tool equipment.

The above objects are accomplished and additional ends are attained by the nove'l construction, combination and arrangement of parts hereinafter described and illus# trated in the accompanying drawings in which 'I have shown one form of the in vention, it being understood that the invention is capable of various adaptations andA that changes and modifications may be made or resort had to substitutions and equivalents which come within the scope of the claims hereunto appended.

In the-drawings like numerals of vrefer'- -ence are employed'to designate like parts 'as the same may appear in any of the several views and in 'whichz-f Figure 1 is anend vviewof 'a radiator constructed in accordance with this mvention,

Figure 8 is a fragmentary viewA showing in horizontal cross section, a modified lform of the invention. n l l Proceeding now t'o a detailed description of the invention with reference to the par` ticular adaptation thereof disclosed in the drawings, the main bod of the radiator is composed of laminae o sheet `metall laminae com rises two similar plates 10 and 11. Each'og) preferably by stamping and differ' only'in that the plate 11'is somewhat longer and` 'lllias a larger -marginal edge than the plate thereof which extends therearound in s aced A relation tothe outer edge thereof 'and orms they plates 10 and 11 are formed The I.

a corresponding groove 15 on the other side thereof. l y The contour and extent of the ,beads 14 and the grooves 15 aree identical in both the plates 10 and llfwhereby the bead 14 will nest in the groove 15 on the adjacent plate "when the parts are `positionedfin abutting relation. The flatumar'ginal edge 16 on the plate 11` is substantially wider than the mar*- ginal edge 17 on .the plate 10. ,A plurality of plates 10 are positioned in flat abutting relation with one of the :plates 11. A plate l i 10 is then added and another plate '11 is positioned in, flat abutting relation therepositioned throughsuitable o exiings in the.`

boltto hold the against, thereby forming a groove or seat \18 adapted to receive the inner edge portion of one of the radiating fins 19. Other plates 10 and 11 are added in the same relation to form a radiator body of the desired length.

While the plates 10 and 11 may be of any desired contour to provide a radiator body of any desired shape,.lthey are preferably formed with side edges which converge toward the upper ed es thereof.

` Each radiatingn 19 isprovldedwith an opening 20 which extends from the loWerV edge thereof. The opening 20 conforms -in shape to the size and contour of the plates 10 whereb each of the tins 19 will be snugly receive on aplate 10 and be positioned between the plates 11. Y

When the plates 10 and 11 have been thus placed in flat abutting relation yto form a radiator body of the desired length, aside member 21 is positioned on one side thereof and a side member 22 on the other side thereof. The side member 21 is rovided with a rib 23 which is adapted to t in the oove 15 in the-plate 10 and the side mem er 22 is likewise provided with a groove which is adapted to receive the bead 14. The plates 10 and 11 with theside members 21 and 22 are then placed in apress and are forced in close abutting` relation. A bolt 24 is then side` members 21 and 22 an through the J alined openings 13 in the plates 10 and I,11

and the nuts 25 are threaded on the said lates in fiat abuttin relation. The side p ates 21 and 22 are li ewise rovided at a point .immediately below the lbwer edge of the lates 10 and 11 with alined openings in whic a bolt 26 is positioned and secured by means ofthe nuts 27, thus securel holding the plates 10 and 11 and the sidi; ,members 21 and 22 in assembled relation. Y 45 The side members 21 and 22 are preferably provided at the lower end thereof with flange extensions 28 which form legs adapted to support the radiator on a ioor or other structure. The side late 21 is provided with an inlet nipple 29 w ich is positioned thereon to provide the inlet opening 30 at the lower edge of the cavity of the'radiator. The side member 22 is likewise provided with an outlet nipple 31. A pipe 32 leadin from a` source of steam, hot water or ot er heating Huid is attached to the nipple 29 and anoutlet pipe 33 is o eratively attached to a nipple 31. Suita le valves 34 and 35 may be positioned in the lines 32 y and 33 to regulate and control theoperation 5 with radiating vanes 36 interposed at reguina havin lar intervals therebetween. The portion of each radiating vane-36 which abuts against the plate 10 is exactly like the plate 1l, but extends outwardly to an extent which corresponds to the detachable fin 19 thereby forming a laminated structure in which the radiating fins 36 form a permanent part of the structure. 4 Y

- The lates10 and 11 may be`of any desired s apeand size and may be provided with openings 12 which will form any suitable shape cavity.

While I have shown particular means for holding the laminas in abutting relation, it isunderstood that any suitable means may be employed.

Having thus illustrated my invention and described the same in detail, what I claim as new and desire to secure by Letters Patent 1s r- 1. A radiator comprising thin metal laminse secured in Hat abutting relation, each `lamina having a relatively largel like opening therein, said openings colnciding to form a radiator cavity and end members closing each end of said cavity.

2. In a radiator, metal laminae, each lamina/havin an opening of the samesize and shape an means to secure said laminae in flat abutting relation with said openings coinciding to form a radiator cavlty.

3. In a radiator, a body composed entirely of thin metal laminas certain of said laminas being of .greater area than others, each laman opening of the same size and shape an means to secure said laminarl in flat abutting relation with said openings coinciding to form a radiator cavity.

4. In a radiator, metal laminas, certain of said laminas having a greater area than others, said laminas provided with communicating openings forming a radiator cavity, members for closing the ends of said cavity-and means for securing said members and laminas in assembled relation said openings being of the same size and shape and located with their edges coinciding to form a relatively smooth cavity wall.

5. In a radiator, a radiator body composed of thin metal laminaeof the same thickness, certain of said laminae having a greater area than others, said laminae provided with communicating o enings of like size and shapeforming a ra iator cavity, means for closing the ends of said cavity and-means to holdprovided with communicating openings forming a radiator cavity, means for closing the ends of said cavity and means to hold 4 opening conformin the outlme of a'lamlna of smaller area, sald saidmembers and lamin in assembled relation, the lamin o f vgreater area being regularly interspaced in said bod in pairs with a lamina of smaller area t erebetween to form a oove and a radiator iin detachably mounte in said groove.

7. In a radiator, a radiator body composed of metal lamin, certain of said vlamina?I hav-v ing a greater area than others, said lamina@ provided vvith communicating openings formin a radiator cavity, means for closing the ens of said cavity and means to hold said members and lamin in assembled relation, the lamin. of greater area being regularly Jinterspaced in said body in pairs with a lamina of smaller area therebetween to form a groove and a radiator fn having an in size and shape to fm fitted in said roove.

In testimonylw ereof I have hereunto set my hand.
